LPG – liquid petroleum gas – is a mixture of light oil gas and heavy natural gas components that are being transferred through a pipeline as a liquid under high pressure. Typical LPG contains methane-ethane, propane-butane and pentane-hexane fractions. During pipeline transportation each LPG component is undergoing constant changes related to longitudinal mixing processes. This article presents a method of calculation of the LPG composition at the end of a pipeline when an initial composition of the LPG components at the beginning of the pipeline is known.
